The 587B Series of 120 Volt AC Surge Suppressors is designed for use by the OEM, equipment installer and or maintenance contractor. These modules employ a three stage technology proven to be the most cost effective and reliable method in protecting sensitive electronic equipment from over voltage transients. This series is designed to protect AC powered equipment from the 6,000 volt peak open circuit voltage and 3,000 Amp short circuit current as defined in ANSI/IEEE C62.41, Category C1. The 587B Series offers a high degree of protection against 120 VAC EMI line noise. It is ideal for protecting 400 Volt components because the solid state TVS technology assures that the line-to-neutral voltage will not exceed 400 Volts. While the modules are designed for transient voltage protection, the advanced circuitry will also attenuate the amplitude and slow the rate of rise of high frequency noise acting as an EMI filter. The 587B Series includes differential mode protection, which is effective in reducing interference from line to equipment and are effective in reducing equipment generated noise to meet FCC and VDE interference requirements.
